Externally generated errors during a data read or write can
be asynchronous. This means that the ELR_EL1, ELR_EL2, ELR_EL3,
of r14 entry into the abort handler on such an abort might not hold
the address of the instruction that caused the abort.
The DFAR is UNPREDICTABLE when
an asynchronous abort occurs.
For a load multiple or store multiple operation, the address
captured in the DFAR is that of the address that generated the synchronous
